Just thought I would share what happened to me a few days ago as I think it'd be interesting to read and might even help someone out if they come across this thread.
Three days ago I was pinning a pec for the first time and I was a little nervous. There's a strong subconscious dread in sticking a needle in your pec, at least the first time (now I'm fine with it). Anyway, normal pinning procedure; stuck the pin in, aspirated successfully with no blood to be seen anywhere, then began pushing the plunger in. .3ccs in I started getting tunnel vision and decided to pull out.
After pulling out, dark venous blood began to leak out and I could feel I started to lose consciousness. I turn around and made a run for my bed, needle in hand, and never made it. I just semi crashed/layed down on the floor, passed out for probably a couple seconds, then came to again. I changed heads on the pin and finished it up in a quad.
What a weird feeling. My first time fainting, ever. I just pinned the same pec today successfully but again, blood leaked out after pulling the pin out. Weird. Anyway, this got me to thinking of the possibility of fainting with the pin still in. A friend of mine once passed out during a glute injection (likely caused by his nervousness) and landed on the pin when he hit the floor. Makes me cringe just imagining it, let alone imaging if it had happened in my pec...
Lessoned learned that I will be doing all my injections sitting down from now on, just in case. Has anyone else had any experiences like this?
